STOCK MAGAZINE Filed Dec. 11, 1936 2 Sheets-Sheet 2 wise on the table 10, the pack being supported at the rear by means of a back rest A, Which includes a supporting plate 12. This plate 12 is slidably mounted in frame members B disposed at the opposite ends of the table 10, each frame member consisting of front and rear posts 13 and a side rail 14 cast integrally With said posts. Each side rail 14 is formed with a groove or guideway 15 along its inner side to receive a bearing block u 16, the lower surfac 17 of the guideway pro viding a seat upon which the lower surface of the block 16 slidably bears. As Will be noted in the detailed views of one of the bearing blocks 16, Figs. 3 and 4, each block includes an offset boss 18 formed With an axial bore 19 therein. A carrier shaft 20 is received at its ends in the opposed bosses 18 of the two blocks 16 and is secured with respect to said bosses 18 by set screws 21. This carrier shaft 20 supports the plate 12 of the back rest, said plate being provided with lugs 22 at the rear thereof formed with bores to receive said shaft and provided with thumb-screws 23 adapted to be turned clown against the shaft 20 for secnring the plate with respect thereto.

A winding shaft 24, revolubly mounted at the forward ends of the frame members B in upright extensions 25 thereof, is employed in advancing the back rest A. To this winding shaft 24 are secured a pair of drums C, each consisting of two semi-cylindrical members 26 and 27 (Fig. 6) adapted to fit around the shaft 24. In each drum, a clamping screw 28, free to turn in a bore in the member 26 and in a bore in the Winding shaft 24, is threaded to fit a threaded bore in the member 27. For each drum C, we provide a tape 29, which is adapted to be wound thereon, the forward end of said tape being secured with respect to the drum by clamping the tape between the shaft 24 and the clamping members 26 and 27 constituting said drum. In this connection, it will be seen that Fig. 6 clearly shows one of the tapes 29 clamped about the winding shaft 20 and extending from the clamping members 26 and 27, forming the drum, in a manner to be wound on the drum upon the rotation of the winding shaft. These tapes 29 extend rearwardly from their respective drums C, each being adjustably connected with one of the bearing blocks 16. 18 of each bearing block 16 is formed at the upper side thereof with a saddle-like clamping member 30 having a concave upper surface or seat 31. Complementing this seat is a clamping strap 32 which is gripped against the clamping member 30 by means of screws 33 passing through said strap and threaded in said member 30; In making eachconnection between tape and block the rear portion of the tape is inserted between the clamping membtr and the strap 32. Upon loosening The boss the screws 33, the block 16 may be shifted along the tape to bring the connection betweenblock and tape nearer to or farther from the point of connection between the front end of the tape and its respective winding drum C as may be desired, it being understood, of course, that in turning down the screws 33 a secure connection is made between tape and block at the point desired. The adjustable connections betWeen the tapes 29- and blocks 16 Provicle for variously positioning the back rest A angularly within the magazine. To permitof such angular dispositions of the back rest A and at the same time prevent end play the'reof in the magazine, the blocks 16 are curved at their outer edges 34, saidcurved edges providing abutting surfaces Which bear against the vertical surfaces 35 of the guideways 15 in rails 14.

To accommodate a pack of units differing in depth at the ends of the pack, one end of the back rest must be retracted farther than the other to bring the foremost unit of the pack squarely into the unit receiving plane at the head of the magazine. The appropriate angular ad'ustment of the back restis secured, as a ove indicated, by adjusting the connections between the tapes 29 and bearing blocks 16. Regardless of the disposition taken by the back rest A in the initial angular adjustment thereoffor a given pack, it remains that the back rest, at the end of its forward sweep, must arrive at a position corresponding With the plane from Which the foremost units of the pack are taken. Ac: cordingly, thelagging end of the back rest Will be moved relatively faster than the other end thereof so that the back rest Will progressively approach parallelism with the unit receiving plane. To accomplish this, we employ a number of adapter rings 36 for the drums 0. These rings,Vary in outside di ameter, but each is like the other in that it is mutilated or slit, as at 37, in order that it may receive and be passed over the winding shaft 24. Each of the various rings 36 is adapted to fit snugly over either of the drms C andin such relation with respect to the drum to which it is applied that the tape 29 secured to the drum may extend through the slit 37 therein.

According to the degree of angularity as sumed by the back rest A in the initial adjustment thereof, an adapter ring 36 of appropriate diameter is selected and applied to the drum C which has the longest length of tape to Wind in. This adapter has the effect of suitably increasing the diameter of the drum to which it is applied and causes the end of the back rest farthest retracted to be moved progressively faster than the other end with the result that the back rest is brought into parallelism with the unit receiving plane at theend of its forward sweep. Thus, the fore:

most unit of a diminishing pack is always presented in the proper position to be taken by the associated eeding element, regardless of the degree of irregularity of the pack resulting in the assembly of units varying in thickness at their opposite ends.

As in our previons invention (Patent No. 1,694,015), the present device includes side guides 38 for a pack within the magazine, said guides being adj ustably mounted at their rear 25 and the gauge 42 being suspended from said rock-shaft.

From the foregoing, it will be understood that'we have, in the present invention, provided for an initial angular disposition of the back rst within the magazine structure,

whereby any given irregular pack madeup of units 0l. greater thickncss at one end thereof than at the other may beaccommodated and that provision is made whereby the mechanism for moving the back rest is employed to bring it into parallelism with the unit receiving plane, as the back rest is advanced to maintain in that plane the foremost sheet of the diminishing pack.

Changes in the specific form of our invention, as herein discldSed, may be made within the scope of what is claimed without departing from the spirit of our invention.

Having described our invention, what We claim as new and desire to protect by Letters Patent is:
